.-^s THIS BOOK 

has been compiled with a view 
toward giving the trade a convenient 
handbook of tables and information 
frequently required during the day's 
routine business. 

THE INDEX in the front of the 
book has been made as complete as 
possible. The character of the sub- 
ject matter, however, makes it im- 
possible to index every item of in- 
formation given without making the 
index almost as large as the book 
itself. To facilitate ready reference, 
we have also provided a thumb index 
and have classified the subject matter 
under the following headings : 

Section I — Prices and Extras 
Section II — Weights 
Section III — Standard Specifications 
Section IV — General Data 

We want this book to be of real 
service to you. Perhaps there are 
other tables or information which 
you require daily but which are not 
contained in this book. If so, we will 
be glad to send them to you and, if 
possible, include them in the next 
issue of this book.

STEEL FOR IMMEDIATE SHIPMENT 25 



PLATES— Cont. 

Hull Plates to Hull specifications required to stand cold flang- 
ing take extras for flange steel. 

CUTTING EXTRAS 

Cutting to lengths 3 ft. and over No extra 

Cutting to lengths under 3 ft. down to 2 ft., inclusive $0.25 

Cutting to lengths under 2 ft. down to 1 ft., inclusive 50 

Cutting to lengths under 1 ft 1.55 

REGULAR SKETCHES 

With not more than four straight cuts, including straight, 
taper plates, length 3 ft. and over $0.10 

IRREGULAR SKETCHES 

With more than four straight cuts, length 3 ft. and over . . . $0.20 

Sketches cannot be sheared with re-entrant angles. 

All sketch plates (other than those sheared to a radius) will be 
invoiced at actual weight of the sketch, at the base price, plus 
standard card extras (including sketch extras mentioned above), 
with an additional charge for waste, if any, to be determined by 
deducting the actual weight of each sketch from the estimated 
table weight of the smallest rectangular plate from which the 
said sketch can be secured, the difference being invoiced at the 
rectangular plate price, less an allowance for the value as scrap, 
which allowance shall be 40% of the base price of rectangular 
plate. 

This 40% is the average ratio between No. 1 Heavy Melting 
Steel Scrap and finished plate prices in the United States over 
a period of 15 years. 

Sketches sheared to a radius take circle extras. 

NOTE. — The "rectangular plate price" at which the difference 
is to be invoiced, is held to be the net price f. o. b. Mill, which 
the maker would have realized had the rectangle been shipped 
to the same destination as the sketch cut from it. Such price is 
properly figured by adding to the Pittsburgh base price the full 
extras for size, gauge, quality and cutting to length, and the 
carload freight rate from Pittsburgh to destination; and then 
deducting the carload freight rate from maker's mill to destination. 

CIRCLES 

Diameters 3 ft. and over, 25% of base price. 

Half circles take circle extras. 

Sketches or circles over 100 in. in width or diameter take 
width extras in addition to sketch or circle extras. 

All sketches, regular, irregular, circular, semi-circular or special, 
with greatest dimension under 3 ft. take cutting to length extras 
under rectangular plates in addition to sketch or circle extra. 

Sketches cannot be sheared with re-entrant angles. 

INSPECTION 

Charges for other than mill inspection, such as "Lloyd's" or 
"American Bureau of Shipping," for buyer's account. 

PRESSING STEEL 

This is a quality of plate steel made for ordinary hot-pressing, 
flanging, or bending work. It is preferred that no requirements 
be specified by the purchaser, but that it shall be left to the 
manufacturer to furnish a steel which with proper handling will 
do such work as above specified. This quality is not guaranteed 
to stand stamping, deep-drawing or cold-flanging. 

If the purchaser desires to specify a tensile range of not less 
than 10,000 lbs., he may do so, but thereby assumes responsibility 
for the working of the steel. 

This quality is distinct from flange steel for boiler work, 
which is covered as heretofore.

WEIGHT TEST 

Determination , of coating by weight test is usually conducted 
by weighing a quantity of dry sheets immediately before and 
promptly after galvanizing, so that the amount of spelter dis- 
tributed over the total area of the sheets used for the tests can 
be estimated in terms of per sq. ft. 

SPOT TEST 

Determination of coating by spot test is usually conducted 
by the lead acetate method. It is understood by the galvanizer 
that the lightest spot on any sheet must not fall below the stipu- 
lated minimum called for by the specification. 



EXTRAS FOR COATINGS SUBJECT TO SPOT TEST 

25 % added to the gross extra for the stipulated coating.

COLD DRAWN SEAMLESS STEEL TUBING. FOR 
MECHANICAL PURPOSES 

Cold Drawn Seamless Steel Tubing is now being used exten- 
sively for various mechanical and engineering purposes. It is 
made of high-grade material so that it machines readily and cuts 
free' and clean. Owing to its smooth finish and slight variation 
in diameter and gauge it can be often used to advantage in place 
of parts usually machined from solid stock. 

We can furnish promptly from Chicago stock any standard 
size of mechanical tubing required, and can secure special sizes 
promptly from the mill.

. CHEMICAL DETERMINATIONS 

3. In order to determine if the material conforms to the chemical 
limitations prescribed in paragraph 2 herein, analysis shall be made* 
by the manufacturer from a test ingot taken at the time of the 
pouring of each melt or blow of steel, and a correct copy of such 
analysis shall be furnished to the engineer or his inspector. 

YIELD POINT 

4. For the purposes of these specifications, the yield point shall 
be determined by careful observation of the drop of the beam of the 
testing machine, or by other equally accurate method. 



FORM OF SPECIMENS 

5. (a) Tensile and bending test specimens may be cut from 
the bars as rolled, but tensile and bending test specimens of deformed 
bars may be planed or turned for a length of at least 9 inches if 
deemed necessary by the manufacturer in order to obtain uniform 
cross-section. 



STEEL FOR IMMEDIATE SHIPMENT 83 



STANDARD SPECIFICATIONS FOR CONCRETE 
REINFORCEMENT BARS— Continued 

(b) Tensile and bending test specimens of cold-twisted bars shall 
be cut from the "bars after twisting, and shall be tested in full size 
without further treatment, unless otherwise specified as in (c), i*i 
which case the conditions therein stipulated shall govern. 

(c) If it is desired that the testing and acceptance for cold-twisted 
bars be made upon the«hot-rolled bars before being twisted, the hot- 
rolled bars shall meet the requirements of the structural steel grade 
for plain bars shown in this specification. 



NUMBER OF TESTS 

6. At least one tensile and one bending test shall be made from 
each melt of open-hearth steel rolled, and from each blow or lot of 
ten tons of Bessemer steel roiled. In case bars differing % inch 
and more in diameter or thickness are rolled from one melt or blow, 
a test shall be made from the thickest and thinnest material rolled. 
Should either of these test specimens develop flaws, or should the 
tensile test specimen break outside of the middle third of its gauged 
length, it may be discarded and another test specimen substituted 
therefor. In case a tensile test specimen does not meet the specifi- 
cations, an additional test may be made. 

(d) The bending test may be made by pressure or by light blows. 



MODIFICATIONS IN ELONGATION FOR THIN AND THICK 
MATERIAL 

7. For bars less than J% inch and more than % inch nominal 
diameter or thickness, the following modifications shall be made in 
the' requirements for elongation: 

(e) For each increase of x /% inch in diameter or thickness above 
% inch, a deduction of 1 shall be made from the specified percentage 
of elongation. 

(f) For each decrease of J^ inch in diameter or thickness below 
74> inch, a deduction of 1 shall be made from the specified percentage 
of elongation. 

(g) The above modifications in elongation shall not apply to 
cold-twisted bars. 



NUMBER OF TWISTS 

8. Cold-twisted bars shall be twisted cold with one complete 
twist in a length equal to not more than 12 times the thickness of 
the bar. 

FINISH 

9. Material must be free from injurious seams, flaws or cracks, 
and have a workmanlike finish. 



VARIATION IN WEIGHT 

10. Bars for reinforcement are subject to rejection if the actual 
weight of any lot varies more than 5 per cent over or under the 
theoretical weight of that lot.

STEEL FOR IMMEDIATE SHIPMENT 



87 



A. S. M. E. SPECI FICATIONS FOR BOI LER PLATE STEEL 
— Continued. 

c. The yield point shall be determined by the drop of the beam 
of the testing machine. 

29 Modifications in Elongation, a. For material over % inch 
in thickness, a deduction of 0.5 from the percentages of elongation 
specified in Par. 28a, shall be made for each increase of J^ inch in 
thickness above % inch to a minimum of 20 per cent. 

b. For material x /i inch or under in thickness, the elongation shall 
be measured on a gage length of 24 times the thickness of the spec- 
imen. 

30 Bend Tests, a. Cold-bend Tests — The test specimen shall 
bend cold through 180 degrees without cracking on the outside of 
the bent portion, as follows: For material 1 inch or under in thick- 
ness, flat on itself; and for material over 1 inch in thickness, around 
a pin the diameter of which is equal to the thickness of the specimen. 

b. Quench-bend Tests — The test specimen, when heated to a 
light cherry red as seen in the dark (not less than 1,200 degrees fahr.) 
and quenched at once in water the temperature of which is between 
80 degrees and 90 degrees fahr., shall bend through 180 degrees 
without cracking on the outside of the bent portion, as follows: For 
material 1 inch or under jn thickness, flat on itself; -and for material 
over 1 inch in thickness, around a pin the diameter of which is 
equal to the thickness of the specimen. 

31 Homogeneity Tests. For firebox steel, a sampleitaken from 
a broken tension test specimen shall not show any single seam or 
cavity more than 34 inch long, in either of the three fractures ob- 
tained in the test for homogeneity, which shall be made as follows: 

The specimen shall be either nicked with a chisel or grooved on a 
machine, transversely, about 3d6 mcn deep, in three places about 2 
inches apart. The first groove shall be made 2 inches from the 
square end; each succeeding groove shall be made on the opposite 
side from the preceding one. The specimen shall then be firmly held 
in a vise, with the first groove about }/i inch above the jaws, and the 
projecting end broken off by light blows of a hammer, the bending 
being away from the groove. The specimen shall be broken at the 
other two grooves in the same manner. The object of this test is to 
open and render visible to the eye any seams due to failure to weld or 
to interposed foreign matter, or any cavities due to gas bubbles in 
the ingot. One side of each fracture shall be examined and the 
length of the seams and cavities determined, a pocket lens being 
used if necessary. 

32 Test Specimens. Tension and bend test specimens shall be 
taken from the finished rolled material. They shall be of the full 
thickness of material as rolled, and shall be machined to the form 
and dimensions shown in Fig. 1; except that bend test specimens 
may be machined with both edges parallel.

flaws, it may be discarded and another specimen substituted. 



88 JOSEPH T. RYERSON & SON 



A. S. M. E. SPECIFICATIONS FOR BOILER 
PLATE STEEL— Continued 

c. If the percentage of elongation of any tension test specimen 
is less than that specified in Pars. 28 and 29, and any part of the 
fracture is outside of the middle third of the gaged length, as indicated 
by the scribe scratches marked on the specimen before testing, a 
retest shall be allowed. 

IV. PERMISSIBLE VARIATION IN GAGE 

34 Permissible Variation. The thickness of each plate shall not 
vary under the gage specified more than 0.01 inch. The overweight 
limits are considered a matter of contract between the steel manu- 
facturer and the boiler builder. 

V. FINISH 

35 Finish. The finished material shall be free from injurious 
defects and shall have a workmanlike finish. 

VI. MARKING 

36 Marking, a. Each shell plate shall be legibly stamped by 
the manufacturer with the melt or slab number, name of manu- 
facturer, grade and the minimum tensile strength of the stipulated 
range as specified in Par. 28, in three places, two of which shall be 
located at diagonal corners about 12 inches from the edge and one 
about the center of the plate, or at a point selected and designated 
by the purchaser so that the stamp shall be plainly visible when the 
boiler is completed. 

b. Each head shall be legibly stamped by the manufacturer, in 
two places, about 12 inches from the edge, with the melt or slab 
number, name of manufacturer, grade, and the minimum tensile j 
strength of the stipulated range as specified in Par. 28 in such manner 
that the stamp is plainly visible when the boiler is completed. 

c. Each butt strap shall be legibly stamped by the manufacturer ■ I 
in two places on the center line about 12 inches from the ends with j | 
the melt or slab number, name of manufacturer, grade, and the 
minimum tensile strength of the stipulated range as specified in 
Par. 28. 

d. The melt or slab number shall be legibly stamped on each test 
specimen. 

VM. INSPECTION AND REJECTION 

37 Inspection. The inspector representing the purchaser shall 
have free entry, at all times while work on the contract of the pur- 
chaser is being performed, to all parts of the manufacturer's works 
which concern the manufacture of the material ordered. The manu- 
facturer shall afford the inspector, free of cost, all reasonable facilities 
to satisfy him that the material is being furnished in accordance 
with these specifications. All tests (except check analyses) and in- 
spection shall be made at the place of manufacture prior to shipment, 
unless otherwise specified, and shall be so conducted as not to inter- 
fere unnecessarily with the operation of the works. 

38 Rejection, a. Unless otherwise specified, any rejection based 
on tests made in accordance with Par. 27 shall be reported within 
five working days from the receipt of samples. 

b. Material which shows injurious defects subsequent to its 
acceptance at the manufacturer's works will be rejected, and the 
manufacturer shall be notified. 

39 Rehearing. Samples tested in accordance with Par. 27, 
which represent rejected material, shall be preserved for two weeks 
from the date of the test report. In case of dissatisfaction with the 
results of the tests, the manufacturer may make claim for a rehearing 
within that time.

STEEL FOR IMMEDIATE SHIPMENT 95 

LLOYD'S SPECIFICATION 

QUALITY.AND TESTING OF SHIP STEEL 

Section 3. 1 — Process of Manufacture. — Steel for Shipbuilding 
shall be made by the Open Hearth process, Acid or Basic. 

2 — Freedom from Defects. — -The finished material shall be free 
from cracks, surface flaws, and lamination. It shall also have a 
workmanlike finish, and must not have been hammer-dressed. 

3 — Testing and Inspection. — The following tests and inspec- 
tions shall be made at the place of manufacture prior to dispatch; 
but, in the event of any of the material proving unsatisfactory in 
the course of being worked into vessels, such material shall be 
rejected, notwithstanding any previous certificate of satisfactory 
testing, and such further tests of the material from the same 
charge may be made as the Surveyor may consider desirable. 

4 — Tensile Test Pieces. — The tensile strength and 'ductility 
shall be determined from Standard test pieces cut lengthwise or 
crosswise from the rolled material. When material is annealed 
or otherwise treated before despatch, the test pieces shall be 
similarly and simultaneously treated with the material before 
testing. 

Plates. — Wherever practicable the rolled surfaces shad be 
retained on two opposite sides of the test piece. The elongation 
ehall be measured on a standard test piece having a gauge length 
of 8 inches. 

For material more than .875 inch in thickness the width of 
the test piece between the gauge points shall not exceed 1 y% 
inches; for material .875 inch to .375 inch in thickness, inclusive, 
the width shall not exceed 2 inches; for material less than .375 
inch in thickness the width shall not be more than 2 J^ inches - 
In other respects the test pieces shall conform generally to the 
Standard test piece A.

j<-FaiaUel for a length of not less than 3 in>>S 
■ -> TOTAL LENGTH ABOUT 18". - - f >! 



Any straightening of test pieces which may be required shall' 
be done cold. 

5 — Mechanical Tests and Selection of Test Pieces. — Plates 
and bars for shipbuilding shall comply with the following mechani- 
cal tests. All test pieces shall be selected by the Surveyor and 
tested in his presence, and he shad satisfy himself that the 
conditions herein described are fulfilled. 

6 — Tensile Tests. Plates. — The tensile breaking strength of 
steel plates, determined from Standard test pieces, shall be 
between the limits of 28 and 32 tons per square inch. For 
plates specially intended for cold flanging and marked for identi- 
fication, the tensile strength shall be between the limits of 26 
and 30 tons per square inch. In the case of material for pur- 
poses in which tensile strength is not important, the tensile test 
may be dispensed with and the bend test only be made, if so 
specified by the builders and approved by the Committee. The 
elongation, measured on a Standard test piece having a gauge 
length of 8 inches, shall not be less than 20 per cent for material 
of .375 inch in thickness and upwards, and not less than 16 
per cent for material below .375 inch in thickness. 

Angles, Bulb Angles, Channels, etc. — The tensile breaking 
strength of sectional material, such as angles, bulb angles, 
channels, etc., shall be between the limits of 28 and 33 tons pep 
square inch. In the case of material for purposes in which 



96 JOSEPH T. RYERSON & SON 



LLOYD'S SPECIFICATIONS— Cont. 

tensile strength is not important, the tensile test may be dis- 
pensed with and the bend test only be made, if so specified by 
the builders and approved by the Committee. The elongation 
measured on a Standard test piece having a gauge length of 
8 inches shall not be less than 20 per cent for material of .375 

^inch in thickness and upwards, and not less than 16 per cent 

"for material below .375 inch in thickness. 

Rivet Bars. — The tensile breaking strength of steel rivet bars, 
when required by the Committee to be tested, shall be between 
the limits of 25 and 30 tons per square inch of section, with an 
elongation of not less than 25 per cent of the gauge length of 
eight times the diameter of the test piece, measured on the 
Standard test piece B, or 30 per cent measured on the Standard 
test piece C. The bars may be tested the full size as rolled.

When the Surveyor is in constant -attendance at the Steel 
Works the following requirements are to be complied with: 

7 — Number of Tensile Tests. — Plates and Sectional Material. — 
One tensile test for plates or sectional material shall be taken 
from the finished material of each charge. 

When the quantity of the material from one charge exceeds 
25 tons, a second tensile test will be required; also additional 
tests shall be made for every variation in thickness of .15 of an 
inch in the plates or sectional bars from each charge. 

Rivet Bars. — When required by the Committee to be tested, 
one tensile test shall be taken from each charge used for rivet 
bars; but when the weight of the bars, as rolled, from one charge 
exceeds 10 tons, an additional tensile test shall be made for each 
further 10 tons or portion thereof. 

Should a tensile test piece break outside the middle half of its 
gauge length, and the elongation be less than that required by the 
Rules, the test may, at the maker's option, be discarded and 
another test be made of the same plate or bar. 

S — Bend Tests. — Cold Bends. — Test pieces shall be sheared 
lengthwise or crosswise from piates or bars, and shall noi be less 
than 1 H inches wide, but for small bars the whole section may 
be used. For rivet bars bend tests are not required. 

Temper Bends. — The test pieces shall be similar to those used 
for cold bend tests. For temper bend tests the samples shall be 
heated to a blood red and quenched in water at a temperature 
not exceeding 80 degrees Fahrenheit. The color shall be judged 
indoors in the shade. 

In all cold bend tests, and in temper bend tests on samples 
.5 inches in thickness and above, the rough edge or arris caused 
by shearing may be removed by filing or grinding, and sampies 
1 inch in thickness and above may have the edges machined, 
but the test pieces shall receive no other preparation. The test 
pieces shall not be annealed unless the material from which they 
are cut is similarly annealed, in which case the test pieces shall 
be similarly and simultaneously treated with the material before 
testing.

LLOYD'S SPECIFICATIONS— Cont. 

For both cold and temper bends the test pieces shall withstand, 
without fracture, being doubled over until the internal radius is 
equal to 114 times the thickness of the test piece, and the sides 
are parallel. ■ 

For small sectional material these bend tests may be made 
from the flattened bar. 

Bend tests may be made either by pressure or by blows. 

9 — Number of Bend Tests. — A cold or temper bend test shall 
be made from each plate or bar as rolled, and these tests shall be 
in about equal numbers from each charge; but a cold bend test 
shall be made from all plates which are specially marked for cold 
flanging. 

10 — Tests for Manufactured Rivets — Rivets selected by the 
Surveyor from the bulk shall withstand the following tests: 

(a) The rivet shanks are to be bent cold, and hammered until 
the two parts of the shank touch in the manner shown in Fig. 1, 
without fracture on the outside of the bend. 

(b) The rivet heads are to be flattened, while hot, in the 
manner shown in Fig. 2, without cracking at the edges. The 
heads are to be flattened until their diameter is 2 }4 times the 
diameter of the shank. 





Fig. 2. 



11 — Additional Tests before Rejection. — Should any of the 
test pieces first selected by the Surveyor not fulfill the test require- 
ments, two further tests may be made from the same plate or bar, 
but should either of these fail, the plate or bar from which the 
test pieces were cut shall be rejected. In all such cases further 
tests shall be made before any material from the same charge 
can be accepted. 

12 — Branding. — Every plate and bar shall be clearly and dis- 
tinctly marked by the maker in two places with the Society's 
brand, thus: 




indicating that the material has complied with the Society's 
tests. 

No plates or bars bearing this brand shall be forwarded from 
the Steel Works until the prescribed tests have been made by 
the Surveyor, and the mill sheets have been signed by him. 
All plates and bars shall also be legibly stamped in two places 
with the Maker's name or trade mark and the place where made. 
They shall also be stamped with numbers, or identification marks, 
by which they can be traced to the charge from which the material 
was made. 

13 — Maker's Certificate. — Before the mill sheets are signed by 
the Surveyor the Maker shall furnish him with a certificate 
guaranteeing that the material has been made by the Open 
Hearth process, and that it has been subjected to, and withstood 
satisfactorily, the tests above described, in the presence of the 
Surveyor. The following form of certificate will be accepted 
if printed on each mill sheet with the name of the firm, and 
initialled by the Test House Manager. 

"We hereby certify that the material described below has 
been made by the Open Hearth process, and is that which has 
been satisfactorily tested in the presence of the Surveyor 
in accordance with the Rules of Lloyd's Register."

LLOYD'S SPECIFICATIONS— Cont. 

14 — Rejected Material. — In the event of the material failing, 
in any case, to withstand the prescribed tests, the Surveyor shall 
see that the Society's brand stamped on the plates and bars by 
the Maker has been defaced by punch marks extending beyond 
the brand in the form of a cross, thus : 




denoting that the material has been rejected. 

15 — Facilities for Inspection. — The Maker shall adopt a sys- 
tem of marking the ingots, billets, slabs, plates, bars, etc., which 
will enable all finished material to be traced to the original 
charge, and the Surveyor must be given every facility for tracing 
all plates and bars to their respective charges, and for witnessing 
the required tests. When he is satisfied with the material and 
with the results of the tests, he shall be furnished with two copies 
of the advice notes of the material for his signature, o,ne of which 
is to be forwarded by the Manufacturer to the Shipbuilder, and 
the other is to be forwarded by the Surveyor to the Surveyors 
at the port where the vessel is to be built. 

16 — Steel not Produced Where Rolled. — Where steel is not 
produced in the works at which it is rolled, a certificate shall be 
supplied to the Surveyor stating the Open Hearth process by 
which it was made, the name of the Steel Maker who supplied 
it, also the numbers of the charges, for reference to the books of 
the Steel Maker. The number of the charge shall be marked 
on each ingot or billet for the purpose of identification, and the 
finished plates and bars shall also be legibly stamped in two 
places with the maker's name or trade mark and the place where 
made. They shall also be stamped with numbers or identifica- 
tion marks by which they can be traced to the charge from 
which the material was made. 

17 — Occasional Attendance at Steel Works. — When the 
Society's Surveyor is not in constant attendance at the Steel 
works, the Makers themselves may, with the written authority 
of the Society, comply with all the foregoing requirements, and 
shall furnish the Surveyor with a certificate to the effect that 
the Society's Rules as to the testing of steel have been complied 
with in the case of the material submitted for approval. The 
Surveyor shall then make check tensile, cold, and temper bend 
tests from not less than one plate or bar in every batch of 50 
or less number, provided the batch be all from one charge. If 
more than one charge is represented, each charge shall be tested. 
Additional tests shall also be made for every variation in thick- 
ness of .15 of an inch made from one charge. The test pieces 
shall be selected by the Surveyor from the plates or bars, and not 
from sheaiings previously detached from them, and when marked 
by the Surveyor for testing they shall be followed, as far as 
practicable, through the different stages of preparation until the 
tests are completed. 

Should the tests be unsatisfactory, the whole of the material 
from the charge shall be rejected, and the Surveyor shall see 
that the Society's brand is satisfactorily defaced. 

18 — General. — Besides the foregoing tests, samples of all 
material may be subjected to additional tests at the discretion 
of the Surveyors. 

19 — In cases wherein it may be desired by Owners and Builders, 
consideration will be given by the Committee to proposals for 
the use of steel of othei tenacity than is provided for in the 
foregoing Rules.

GENERAL DATA 



DEFINITIONS OF COMMON TERMS 

Tensile Strength. — (Ultimate or Maximum Stress). Maximum 
load material can sustain in tension without fracture. 

Elastic Limit is the maximum stress a material can bear without 
permanent distortion or set. Within certain limits, steel is an 
elastic body and on being elongated by a tensile strength, returns 
to its original dimensions when the force ceases to be applied. 

Elongation is the increase in length which a metal bar undergoes 
when subjected to a tensile stress sufficient to cause fracture. 

Reduction of Area is the amount of contraction of area which takes 
place at the point of fracture when a metal bar is broken by a 
direct pulling force. Both the elongation and reduction of area 
furnish valuable indications of the ductility of steel; the greater 
they are for the same class of material, the softer and more ductile 
the material may be considered. 

Yield Point in ordinary commercial practice is the same as the 
elastic limit. 

Red Shortness. — Steel to be free from "red shortness" must be 
capable of being worked at all temperatures from a red to a welding 
heat without showing any signs of cracking or other defects. 

Cold Shortness. — Steel to be free from "cold shortness" must not 
show any signs of brittleness under sudden shock, or under a 
steadily applied load in the cold condition, the stress which such 
steel may reasonably be expected to bear varying with its carbon 
content. 

Steel is a chemical compound of iron and carbon; that is, it contains 
no carbon in a free state as cast iron does. Its tensile strength is 
greater than that of wrought iron, and its compressive strength 
greater than that of cast iron. Steel, unlike wrought iron, is 
fusible; unlike cast iron, it can be forged, and with the exception 
of the higher grades it can be welded by heating and hammering, 
although care must be exercised in so doing. 

Effect of Carbon on Steel. — Increasing the carbon content in- 
creases the tensile strength, as will be noted from the following 
table. 

'Effect of Sulphur on Steel. — When sulphur is over .06 there is 
a tendency to red shortness. Numerous cracks are liable to de- 
velop during rolling, which are imperceptible in the finished 
material, but which may later form starting points for rupture 
when material is subject to sudden stress. 

Free cutting steel, for threading and screw machine work, is ob- 
tained by increasing sulphur content to about .075 to .10. 

Effect of Phosphorus on Steel. — Produces brittleness and gen- 
eral cold shortness. On account of its treacherous nature it may 
be -stated that the lower the phosphorus, the better the grade 
of the steel. 

Effect of Manganese on Steel. — Manganese is added in the 
making of steel to prevent red shortness and in ordinary grades 
of steel ranges from about .30 to .60. 

(When manganese is present in large amount, 7% and over, a GENERAL 
special steel is produced, possessing great hardness. ^„J^ 

Effect of Silicon. — In commercial practice the silicon present in 
steel is very slight and may be considered negligible as affecting 
the physical properties.

NOTES ON CORRUGATED SHEETS 

TO ASCERTAIN LENGTH OF A CURVED SHEET 
BY FOLLOWING TABLE 

Rule. — Divide height (or size) by base (or span), find quotient 
in column of heights, take length for chat height opposite to it in 
next column on the right hand. Multiply length thus obtained by 
base (or span) and product will give length of sheet. 

Example. — Find length of sheet, base (or span) being 100 inches, 
rise being 25 inches. 

25 divided by 100 equals .25; and .25, per table, equals 1.15912, 
length of base, which multiplied by 100 equals 115.912 inches, length 
of sheet before curving.

NOTES ON CORRUGATED SHEETS— Continued. 

To find the Rise when radius length of Span is given, use 
following formula:— 




V=Ii- VR2- C 2 or nearly 



To find length of Arc when Span and Rise are given: 



-£1 

8R 




L — Length of Arc ^ 

C— Span L = * C ~" U 

c— Small Chord 3 



To find the Rise when radius and length of Arc Is given, 
use following formula: — 

Rise = Radius — Cosine of Angle X 




Y = 



R 



Arc x 360° 
Cir. 

Y

The above are approxi- 
mate figures on 1 M in- and 
2 H in. Corrugations. 



One pound of nails and Y% pound of washers are required to lay 
one square. 

One gallon of paint will cover approximately 400 sq. ft. of 
roofing 

304 lead washers equals 1 pound. 

165 1 l A. x No. 10 Roofing Nails ecmals 1 pound. 

To find width of sheet before corrugating multiply width of 
sheet after corrugating by 1.08.

Nuts and bolt heads are de 
termined by the following rules 
which apply to both square and 
hexagon nuts : 
Short dia. of rough nut 

= l^Xdia. of bolt+^g in. 
Short dia. of finished nut 

= l^Xdia. of bolt+^in. 
Thickness of rough nut 

= dia. of bolt. 
Thickness of finished nut 

= dia. of bolt+M in- 
Short dia. of rough head 

= l^Xdia. of bolt+H in- 
Short dia. of finished head 

= l^Xdia. of bolt+Min. 
Thickness of rough head 

= A short dia. of head. 
Thickness of finished head 

= dia. of bolt+M in. 

The long diameter of a 
hexagon nut may be obtained 
by multiplying the short di- 
ameter by 1.155 and the long 
diameter of a square nut by 
multiplying the short diam- 
eter by 1.414. 

The above standards for 
screw threads, nuts and bolt 
heads were recommended by 
the Franklin Institute in De- 
cember, 1864. The standard 
for screw threads has been 
very generally adopted in the 
United States, but the pro- 
portions recommended for nuts 
and bolt heads have not found 
general acceptance because of 
the odd sizes of bar — not usual- 
ly rolled by the mills — re- 
quired to make the nut.

TRADE CUSTOMS 

Quotations 

All quotations are subject to change without notice, and all 
sales are made subject to strikes, accidents, or other unavoidable 
dciiiys. 

We reserve the right to cancel contracts not fully specified in 
time agreed upon. 

Special material is not subject to cancellation without our 
written consent. 

Confirmation Orders 

Confirming orders should be marked Confirmation — preferably 
across face of order. Confirmation orders not so marked may 
be treated as original open orders and duplicated — in such cases 
we will not be responsible for expense and inconvenience incurred. 

Terms 

Our terms are one-half of one per cent, for cash in ten days or 
net cash in thirty days from date of shipment, unless otherwise 
agreed upon. All payments to be made by bank draft on Chicago 
or New York, U. S. Treasury notes or their equivalent. Strangers , 
should accompany their first order with cash or references. 

Deliveries 

Material from our warehouse is usually shipped the day order I 
is received. 

Orders by telephone are accepted at the risk of the sender, as : 
shipments made before receipt of confirmation are for the service 
of the customer. 

Promises on special work or material from mill are as closely I 
estimated as possible, and we use our best efforts to ship within 
the time, but can not guarantee to do so. 

Clai ms 

A clear receipt from the railroad places the responsibility for 
shortage or damage with the carrier, and, if there is any dis- 
crepancy, your local station agent should be requested to note 
on the freight bill before it is paid. This will enable you to re- 
cover on any Legal claim- 
Carloads are usually forwarded on " Shipper's Load and Count" 
and should, therefore, be carefully checked while unloading and 
the railroad agent immediately notified in case of any shortage 
or damage. 

Shipments by land, lake or river will be insured only when 
buyers so instruct — otherwise, we are not responsible for loss or 
damage, after receiving a clear shipping receipt for the goods. 

Claims for defective material should be made immediately 
upon receipt of the goods. Transportation Companies will not 
accept or pay claims unless filed within six months (freight) or 
four months (express). 

Crating 

"C" Pickled, Extra Deep, Auto Body and Lead Finish Sheets 
will bfe crated for shipment unless instructed to the contrary. 
On large orders where we can induce railroad to load carefully 
in box car without transferring, crating charges can be elimin- 
ated. Following are charges per crate, based on 500 lbs. or less 
per crate. Skeleton crates will be used unless otherwise in- 
structed. 

Size Skeleton Full 

All Stock 50 cents per 100 SI. 15 per 100 

size sheets lbs. net weight lbs. net weight 

of sheets of sheets 

Minimum charge Minimum charge 

$2.50 $5.75 

Packing „ , 

Boxing is charged on all small or broken lots. 

Defective Material . 

All our material and fittings are carefully inspected and our 
machinery tested before shipment, but in spite of the greatest 
care it is sometimes impossible to detect all imperfections. We 
guarantee to replace, with new material, such goods as prove de- 
fective within a reasonable time, when properly worked or used, 
but under no circumstances will we be responsible for any dam- 
ages beyond this. All material claimed defective must be held 
for our inspection and disposition. No charges for labor or 
expense required to repair defective goods or occasioned by them 
will be allowed, the measure of the damages being the price of the 
defective article. 

Boiler Construction 

In the construction of boiler and pressure tanks. Government 
laws and some State laws, require certain chemical and physical 
test reports and the stamping of boiler plates, heads and acces- 
sories with the maker's name and identification marks. If boiler 
construction material is to comply with any of these specifications, 
such information should be placed on the order. We can not 
assume any responsibility other than replacing of material that 
does not conform to necessary requirements used in the construc- 
_ tion of any boiler or pressure tank.
